Answer:
yes given statement is true
light year is a measuring unit of distance
Explanation:
light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000 kilometers.
Why would you want such a big unit of distance? Well, on Earth, a kilometer may be just fine. It is a few hundred kilometers from New York City to Washington, DC; it is a few thousand kilometers from California to Maine. In the universe, the kilometer is just too small to be useful. For example, the distance to the next nearest big galaxy, the Andromeda Galaxy, is 21 quintillion km. That's 21,000,000,000,000,000,000 km. This is a number so large that it becomes hard to write and hard to interpret. So astronomers use other units of distance.
In our solar system, we tend to describe distances in terms of the Astronomical Unit (AU). The AU is defined as the average
Answer:
Ofcourse why not
Light year is a measuring unit of Distance.
u must be thinking how is it possible .it has year in it.
Light year is used to measure large distance in Universe..
(distance covered by light in one year is called light year).
